[German]Adobe has released a hotfix 21.001.20138 for its Adobe Reader and Acrobat DC. This update fixes a number of bugs, including installation error 1722, which I discussed here on the blog a few days ago.
With the security updates from February 9, 2021, some Adobe Reader/Acrobat DC administrators ran into problems, because these updates could not be installed in all scenarios. The installation then failed with installation error 1722- I had pointed out this issue and a workaround in the blog post Adobe Reader/DC Update (Feb. 9, 2021) drops error 1722 in Windows.
